Marsilea batardae, known as Lusitanian Water Clover, is a perennial, creeping aquatic fern resembling a four-leaf clover.

It prefers full sun to partial shade and requires a consistently moist substrate or shallow water immersion (up to 10 cm). Ensure the water is clean and well-oxygenated, avoiding stagnation. A common mistake is allowing the substrate to dry out, which can lead to frond desiccation and weakening of the plant.
